You just don't get it, do you? Calling a device by its (LAN) IP has
no need for registration. Try it some time and see how it goes.

I have been using a similar technique (ie. calling a VoIP device by
IP, which actually is the remote end of a point-to-point VPN) for ages.
This type of communication doesn't need (or leak) anything from
(or to) the internet at large.

As long as the participating VoIP clients don't crash or otherwise
misbehave and the connection channel stays up, whether the registar
knows about their current availability status, IPs and audio ports
(or is able to talk to them at all) is totally irrelevant.

If you need more convincing consider the following scenario: a
VoIP device having multiple IPs (physical or virtual). It publishes one
of them (via the registrar), but (assuming it has been configured to
listen on all of them) it can also be called by anyone on the other
(non-published) networks. Do you get it now?
